[erlang-bugs] megaco flex warning

[Tuncer Ayaz]

There's a warning while processing megaco_flex_scanner_drv.flex:
megaco_flex_scanner_drv.flex:443: warning, the character range [~-ÿ]
    is ambiguous in a case-insensitive scanner

Maybe flex should print decimal or hex values in the character range
instead to make it clearer and potentially more portable.
